Registering a codec for ReactiveMongoClient Spring Boot 2

[Gintas]

Hi,

What is the process to register a codec for a ReactiveMongoClient? 

I use the following snippet to add the OffsetDateTimeStringCodec codec that handles OffsetDateTime type: 

public class MongoConfig extends AbstractReactiveMongoConfiguration {

    @Override
    public MongoClient reactiveMongoClient() {
        CodecRegistry codecRegistry = CodecRegistries.
                fromRegistries(
                        CodecRegistries.fromCodecs(new OffsetDateTimeStringCodec()),
                        MongoClients.getDefaultCodecRegistry()
                );
        ClusterSettings cs = ClusterSettings.builder().hosts(Arrays.asList(new ServerAddress("localhost"))).build();
        MongoClientSettings mcs = MongoClientSettings.builder()
                .codecRegistry(codecRegistry)
                .clusterSettings(cs)
                .build();
        return MongoClients.create(mcs);
    }

   ...
}

I can add documents to the database, but instead of OffsetDateTime I see that the persisted object is identified as Object. 

Am I missing something?

Thanks,
